There are two basic approaches. You can use the "create file" step in the File Utilities plugin. There you would just paste in your file and just put standard ${p:...} properties in the file.

The other is a bit more formal. Components can have file configuration templates. In 6.1, you go to a component > Configuration > Configuration File Templates

Here you tokenize the file by putting @ symbols around property names. By default, properties in the environment are in scope and if the names match, the values are swapped in. You can adjust which collections of properties are in scope under the "Show Hidden Properties" option.

The plugin for loading the template should be installed by default but if you need it, it's here.
